METALLIC RAILWAY-TIE.

Specification of Letters Patent.

Patented Feb. 22, i910.

Application filed May 24, 1909. Serial No. 497,985.

To all whom 'it may concern:

Be it known that I, SIDNEY MoCLoUD, a citizen of the United States, residing at Ghicago, Illinois, have invented certain new and useful Improvements in Metallic Railway- Ties, of which the following, taken in connection with the drawings, is a description.

My invention has for its object the production of a metallic railway tie, one which is an embodiment of strength, durability and etliciency, and is so constructed that it is capable of being placed on the market at a much lower cost than is possible with metal ties now commonly known, the excessive price having heretofore been a serious obstacle in the way of the general use of ties of this class.

A further obj ect of the invention is to produce a tie which shall have sufficient spring or resiliency to withstand the jars and strains caused by moving trains, without overtaXing the tie and cracking or disrupting the metal.

Still a further object is to provide a new and useful means for securing the rail to the supporting member, bracing it, and prevent ing any possibility of tip, slip or sidewise displacement. And yeta further object of the invention is to provide a tie which may readily be disposed in the road bed, evened up and tamped with the ballast to securely hold it in place, provision also being made against endwise movement.

In the accompanying drawings I have illustrated the best embodiments of my invention now known to me, premising, however, that various modifications in detail, and touching the arrangement and construction of the. dierent parts, will suggest themselves to persons skilled in the art relating to this class of devices, and in these drawings- Figure l is a top plan view of the preferred form of my invention; Fig. 2 is a longitudinal sectional view taken upon the corresponding numbered line in the preceding ligure; Fig. 3 is an enlarged sectional detail showing a brace and fastening for the rail, together with the rail and the top plate of the rail supporting member, all in assembled position; Fig 4 is a fragmentary view, taken on line 4:-4 of Fig. 9., showing a portion of a rail in elevation, an end view of the rail supporting member, and a transverse sectional view through the trough of the tie in collocation; Fig. 5 is a view, similar to the preceding, of a modified form of construction, and Fig. 6 is a perspective view of the preferred form of rail supporting member.

In carrying out the invention the tie is formed or built up channeled or tray-shaped, preferably from two oppositely facing angle irons A, A, the ends a, a of which are closed by being bent inwardly toward each other and overlapped, as shown in Figs. l and 2, this construction forming an elongated channel or trough the bottom of which is intended to rest upon the graded road bed. rIhe rail supporting members B, B, are arranged or disposed in this trough a suitable distance apart, with proper relation to the ends of said trough, and are seated between snugs a', a, formed by looping, bending or striking inward the vertical flanges of the angle irons, as indicated in Fig. l.

Secured to the bottom of the tie, at points directly beneath the rails B', B', by bolts or rivets b are anchor plates b, b which have downwardly projecting sides, anchors or lips b', b preferably flaring in the direction of the length of the tie, which extend into the road bed to provide additional gripping surfaces and further prevent or resist any endwise movement or slip of the tie. While these plates are desirable they are not indispensable to the successful use of my invention, and I contemplate constructing the t-ie with or without said plates.

The bottom flanges of the angle irons forming the tie are recessed or cut away at approximately the center of said tie, as at a2, to form an elongated opening which provides sufficient drainage for the trough, allows the ballast to move through vthe tie with the weight of the traffic passing over it, by reason of which the tie is prevented from bending upward in the middle on account of the more direct weightupon the outer ends than in the center, and affords additional security against endwise slip.

The rail supporting members B are formed separately from the trough of the tie, as already indicated, are disposed transversely in said trough, and provide a resilient base upon which the rails rest. These members are each formed of a single piece of material, as shown more clearly in Fig. el, bent into practically a tri-triangular shape and suitably tempered, the center triangle b2 being secured at its base to the bottom of the trough by suitable fastenings, which may be the same bolts or rivets Zi secured Between the bottom of the trough and the outer sides of the triangles b3, b3 of the rail supporting members is a space b4 extending the length of the supporting members. This space' allows springing or flexibility of the outer triangles, permitting a practically vertical movement of the supporting member for automatic adjustment of the tie with respect to the road bed as the weight of the trains on the rails passes over it.

Formed upon the top or chair of the rail supporting members B, preferably integrally therewith, are the lugs or keepers c, c, against which the outer flange c of the rail abuts. The rail is held in position against these lugs by clips c2, c2, taking over the inner flange and bolted to the top of the supporting member. F or curves the lugs c, c, may be replaced by a higher lug B2 projecting above the outer flange of the rail, as indicated in F ig. 3, where it is shown as formed upon the top of the supporting member and abutting against said outer flange. A brace C extends from the chin or reentrant angle of the rail head down to the outer flange, then is bent to sit against and saddle lug B2, and finally is secured by bolts C passing through its flanged end and the top of the supporting member. This makes av very reliable prop to prevent tipping or slewing of the rail as a train swings around a curve, but is not particularly necessary on straight lines.

In Fig. 5 is shown a modified or alternar tive form of the rail supporting member, in which the triangular base D has the ends (l, d bent outwardly and horizontally to form the chair for the rail. In this construction the side walls of the trough member of the tie are bent inwardly to.closely embrace the triangular body of the rail supporting member' and the rail is secured to the latter by clips d and bolts cl2 as shown.

I claim:

1. A metal tie or sleepercomprising two oppositely facing angle irons secured together to form a trough, rail supporting members in said trough, the sides thereof abutting against the vertical flanges of the angles, said vertical flanges of the angles being bent inwardly to form abutments at each end of the rail supporting members.

2. A metal tie or sleeper comprising two oppositely facing angle irons arranged to form a trough, resilient rail supporting members in said trough, said members abutting against the vertical flanges of the angles, and inwardly bent snugs in the vertical flanges of the angles providing abutments against lateral movement of the rail supporting members.

3. A metal tie or sleeper comprising two oppositely facing angle irons arranged to form a trough, rail supporting members carried by said trough member, and plates secured to the bottom flanges of the irons, said plates having anchor lips flaring downwardly and outwardly in Jthe direction of the length of the tie.

l. A metal tie or sleeper comprising two oppositely facing angle irons arranged to form a trough having an elongated central opening through the bot-tom thereof, `resilient rail supporting members in said trough, a lug formed on the chair of each rail supporting member, said rail supporting members being secured to the bottom of the trough, the sides thereof abutting against the vertical flanges of the angles, and inwardly bent snugs on the vertical flanges of the angles providing abutments against lateral movement of the rail supporting members.

5. A metal tie or sleeper comprising oppositely facing angle irons arranged to form a trough, resilient rail supporting members secured inside the trough, lugs formed on said supporting members, and means coacting with said lugs for securing rails to the supporting members.
